COCK FOR HYDRANTS.

SPECIFICATION forming part of Letters Patent N0. 290,132, dated December 11, 17883.

i Application filed April ao', 1883. (No model.)

To all whom, t may concern/.-

Be it known that I, JASPER SNELL, a citizen of the United States, residing at Pottsville, in the county of Schuylkill and State of Pennsylvania, have invented certain new and useful Improvements in Cocks for Hydrants and other Purposes yand I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specication, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a perspective view of my invention, and Fig. 2 a sectional elevation thereof.

llhe present invention has relation to certain new and useful improvements in that class of cocks or faucets provided with a waste, and adapted to hydrants and various other uses to which such class of devices may be found advantageous.

rIlhe object of the invention is to improve the construction of the above-mentioned class of cocks or faucets, whereby superiority is obtained in the manner of waste vand the readiness with which the device may be operated when drawing water, the waste water fiowing through the hollow valve-stem after the valve is closed. These objects I attain by the construction substantially as shown in the drawings, and hereinafter described and claimed.

In the accompanying drawings, A represents the body of the cock or faucet, screw-- threaded at its lower end for convenience of attachment to the water-pipe, the construction shown being especially adapted to a hydrant.

The body A has attached to it a nozzle or Outlet, a, for the discharge of the water, said nozzle or outlet being in .line and communieating with a passage, b, formed in the body.v

To the upper portion of the body A is suitably connected a yoke, B, through which passes a screw-rod, C, the threads thereof engaging with those of a screw-threaded hole in the yoke.

' The body A is formed with an inclined seat, d, against which closes a correspondingly-formed valve, c, by the action of a spring, 5o e, coiled around the lower portion of a valvestem, D. The upper coil of 'the spring e bears against awasher, f, while the lower coil rests upona screw-threaded thimble, g, which forms a guide for the lower end of the valvestem D. The valve-stem is formed with an annular' shoulder, h, against which is kept pressed the valve c by the spring and washer ef. rIhat portion of the valve-stem D above the valve c is formed hollow, to provide an 6o escape, z', for the waste water after the valve has been closed, the escape at its lower end extending horizontally through the side of the stem. The hollow portion ofthe stem D extends up through the top of the body A and through a sleeve, la, connected to or cast with. the body. The construction shown being intended, principally, for use in hydrants, p thehollow portion of the valve-stem and the screw-rod for operating it may be extended 7o to the length of several feet, and the whole to be inclosed in a box or stock, as in all other hydrants. Vhen the valve-stem D is pressed down by the screw-rod C, the valve c will be forced off the seat d, thus allowing the water to pass up and be discharged through the nozzle or outlet a. In closing the valve, the rod C is screwed up to the position as indicated in Fig. 2, when the spring e will automatically close or force the valve c against So the seat d. Thus it will be seen that the moment the valve is opened to allow the discharge of water the escape 13 is closed by the rod C coming in contact with it, and when the valve is closed by the action of the spring it is necessary that the rod should be removed from contact with the hollow end of the valve-stem, thereby allowing the waste water remaining above the valve to escape through the hollow portion of the valve-stem. 9o

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is y A cock or faucet for hydrants or other purposes, consisting of the`body A, formed with a 9 5 passage, b, communicating with the outlet a,

and provided with the yoke B, in combinar In testimony that I eiaim the above I have tion with the valve c, valve-stem D, open at hereunto subscribed my name in the presence its upper end, the serew-r0d C, and the serewof two Witnesses.
